•
If a single calibration test fails or is canceled, the
system prompts for a retest using a new sample.
•
If two failures occur within the same standard
group, that calibration fails and the screen displays
the message
Two replicate failures
.
•
Upon completion of the last calibration test, the
system displays a
Calibration successful
message
or the reason for failure.
6.
Click
OK
to close the success (or failure) message.
•
When you close a success message, the system
returns you to the Home screen.
•
When you close a failure message, the system
clears all checkmarks and returns you to the
Calibration screen. From there, you can restart the
calibration or exit to the Home screen.
When calibration is successful, the instrument calculates
a new calibration slope and intercept and saves those
values to memory.
If a calibration test fails or is canceled for any reason,
the instrument does not save that calibration data;
instead, it maintains the last successful calibration.
The date of the last successful calibration is displayed
on the Calibration screen.
3.5 Canceling calibration
Press at any time to cancel a calibration test in
progress or the entire calibration process.
Canceling the test in progress
To cancel the particular test in progress, retract the
sample handler cradle. The system prompts you to retest
with a new sample.
NOTE:
You can cancel individual tests as often as
necessary. Cancellation of an individual test does
not count toward the limit of two failures within a
calibration set.
Canceling the entire calibration
If you cancel the entire calibration, the instrument
maintains the last successful calibration.
1.
To cancel the entire calibration, press .
A confirmation prompt appears.
2.
At the confirmation prompt, press
Yes
to confirm
cancellation, or
No
to continue calibration.
If you press
Yes
to confirm cancellation, the system
discards any data from this calibration and returns
you to the Home screen.
